D 77, 054027 (2008), we point out that a chiral restoration phase transition in a quarkyonic matter at low temperatures is of second order within a manifestly confining and chirally symmetric large $N_c$ model. This result is qualitatively different as compared to NJL and NJL-like models that are not confining and might have some implications for the existence or nonexistence of the critical end point in the QCD phase diagram.2 pp. A paragraph with a caveat has been addedHigh Energy Physics - PhenomenologyHigh Energy Physics - LatticeNuclear Theorytext
